.'This4 invention relates to shades for i 0 `the invention will be understood more-clearsources of light, and more particularly to ornamental lamp' shades. Ob] ects lof the 1nvention are to rovidell. ornamental novelty shade, utilizingwood with its natural.,

grain/displayed in an effective and pleasing manner; and to treat a sheet of wood employedv in a'shade in such a manner as to increase'- its translucency, durabillty and.

flexibility, so that it will display the .grain ofthe wood to better advantage and w1ll resist the effects of moisture and drying `and will not be subject to objectionable crackln",

. distortion and other .diiculties'g to provi e an unformed blankof wood as an article of commerce adapted to be assembled as a shade by the purchaser; and generally to D an improved and ornamental form o article of the kind referred to.

In accordance with one aspect `of the present invention, a translucent sheet of wood is sup orted to intercept the ra s from a source of) light thereby to disp ay the physical structure of the wood when the adjacent .fibres thereof are in substantially` their original natural relationship. `A fixing substance applied to the sheet of wood' renders the wood translucent or increases its translucency, and increases its flexibility, and

`durability so that it will resist the 'effects'of' moisture, drying, and other factors. A. di-

a hanous medium such as a translucent sheet.

o' fabric adhering to the back of the sheet of wood serves to retain thel adjacent fibres ofthe wood in substantially their original natural relationship, and to Aprevent .cracking, distortion and other diiiiculties resulting vfrom the tendency of different parts of the wood to unequally expand or contract, or re- 4o sulting, from bending the wood. f

In one form of the invention a translucent sheet consisting of a ply of wood and an adhering ply of fabric is formed into a loop, the ends of the loop being fastened together.l By disposing the fibres of the wood in a directionsimilar to thatof the lane of the loop, the strength and ,durabllity of they rovide These and other objectsand features of ly" in view of the following detailed de-v scription and the accompanying drawing, in which:l y

Fig. 2 is a vertical section of Fig. 1;

Fig. 3 is a plan of the u per edge of Fig. 2.

luminated by the electric lamp 3, shown in dotted lines, or by any other suitable source of light. The shade consists of aj sheet of wood of such thinness that it is translucent,

-or of such thinness that when treated toreduce its opacity it is appreciably translucent. In the\ case of many kinds of Wood, it has been found that a' sheet having a thickness as great as fifteen thousandths of an,y inch or greater may be suitably translucent, while sheets of less thickness are more translucent. It will, of course, be understood that the character of the wood and the velements associated therewith in any given case will determine what thickness is required for a given degree of translucency.

A backing ply 4 of diaphanous materialY such yas paper, cloth, or other suitable medium, which may be either translucent or transparent, is cemented to the wood ply 1 b means of translucent paste or other sitable cement. The plies v1 and 4 together form' a'translucent sheet which, in the example here referredto, is formed or bent into a shape corresponding to the frustum of a cone by making a loop of a sheet having the shape shown in Fig. 5, and fastening the ends together by translucent paste or other suitable cement, as indicated by lines 5, Fig. 2. The fabric 4.- is adapted to resist unequal expansion or contraction of different parts of the wood, and to resist the effects of forces set up by bending the wood.. The grain of the Wood is preferably so dispose 1n the ply that the fibres arey directed similarly to .the plane of the loop or to the direction ofmaximum bending as 1nd1cated` roughly by the direction of the dashes I.depicting the grain in Figs.l 1 and 5. Ornamental bands 6 and 7 may consist lof strips of woodply 1 or may be of vother oredges of the loo cement for rein orcing the sheet and for ornamental effect. The loop is retained in a circular form by means of still circular rings 8 and 9 of U-shape or broken circular cross section, orof any'other suitable form. The exposed edge formed by plies 1, 4, and 7 is inserted between the arms of the U, and the arms of the U are then clinched at inteI-, vals orthroughout the extent yof the rings as by spinning lor by forming under pressure. Rings 8 and 9 may be made of steel or any other suitable, material. Spring loops 10and11 held in'rposition by ring 12, are supported by attachment to ring 8 by welding or other means at points 13. These loops are adapted to grasp the to of bulb 3,'

in wellknown manner. It is o vious that any other suitable means may be employed in place of elements 10, 11, and 12.

Fig. 5 shows an unformed blank 14 adapted to be sold in the form indicatedor in The blank illustrated has the shape of other suitable form for assembly by the purchaser. The blank consists of a sheet of translucent wood 15, shown broken away to expose the underlying adhering sheet 16 of diaphanous fabric such as paper, cloth, or the like similar to ply 4 Fig. 2. When assembled, the blank may be decorated in any desired manner by braid (not shown) or other well known forms of ornamentation.

a sector of an annular ring and is adapted to "grain structure inmore detail, to soften the wood and to increase the durabllity, flexibility, and permanency of the shade, so that y constituents of the fixing liquid. The kerosene appears to serve as an agent for acting on the natural oil or sap in the wood and for softening the wood to render it more flexible, whereas the linseed oil serves to seal the pores of the wood to resist the effects of lmoisture and drying and to render the ef- I fectof the kerosene more permanent. Other constituentsr` having like roperties to those named may be substitute A pleasing ornamental effect is produced by sheet 1, owing to the -intricate natural patterns in the wood as displayed after treatment with the liquids, described above and as a result'of the natural coloring of the wood and the 'soft light-eifects produced by unequal diffusion and refraction in different parts of the wood; 'The larger pores of the wood provide points of greater ytranslucency giving the appearance of nu.

It will be noted that the modihcation of the shade shownl in Fig. 4, is similar to the' form shownin Fig. v2, but differs therefrom in omitting band 6 or 7 i If desired, the' wood may be rendered more flexible and. conformable to the supporting rings 8 and 9 of the shade, or to the desired shape, by applying to the wood in any suitable' manner,

Various modifications of `the. species -'of disclosed to illustrate the generic principles of the present invention will be For example, the wood may be dyed any suitable color andsthe backing ply 4 or 16 may be cplored separatel and differently 'fromthe wood. The blanli, 14 may obviously be given a different predetermined contour suitable for constructing a different form of shade.
